Hey this is a great question.
We run a property management company here in the area and what it sounds like is that even though you were not the responsible party on the lease, you were named as well.
What we do normally here when we write the original lease up is name all the parties living in the unit and their ages.
When your mom was served the court eviction papers they included her name and yours because you were now 18... if they didn't name you, they would not have been able to legally remove you from the property because you wouldn't have been "served".
As a previous answer you should send a dispute letter to all 3 of the agencies and start the dispute process. Look up credit repair in a google search and I think you'll find some suggested solutions to rectify this problem.
I hope this helps...
Make it a great day...
If I understood you correctly, you should be able to prove that you were a minor at the time the lease was signed and therefore you could not and were not a party to the lease agreement.
you ask whether "they" (whoever "they" is) have any legal grounds. Well let say they don't have any legal grounds, but they refuse to acknowledge it's not your responsibility, then what??
often it cost money to stand up for/ to defend your rights/to correct a wrong. so injustice can stands firm until the aggrieved person acquires the money needed to have his day in court represented by a competent lawyer.
Equifax should get a reply from the company/entity they contacted regarding your dispute in 30 days. Wait to see the results of your dispute before taking further action.
